  • Patent number: 7153790
    Abstract: A penetration-resistant material is described to include at least a double layer of woven fabric, wherein the double layer includes a first layer of fabric composed of a first set of threads having 3.5 to 20 threads/cm, having a linear density of at least 210 dtex, and composing at least 65% of the first layer fabric weight, and a second set of threads comprising 0.5 to 16 threads/cm and having a linear density of at least 50 dtex, with the second set of threads being transverse to the first set of threads, and the ratio of the number of threads/cm of the first set to that of the second set is greater than 1:1, and a second layer of fabric composed of a first set of threads having 0.5 to 16 threads/cm and having a linear density of at least 50 dtex, and a second set of threads having 3.

  • Publication number: 20040166755
    Abstract: The invention pertains to a laminated ballistic structure having an array of layers of substantially alternating n unidirectional (UD) layers of ballistic fiber and m thermoplastic layers, excluding thermoplastic layers at the outer sides of the structure, wherein ½n≦m<n. The UD layers have 1-25 wt. % of an elastomeric material based on a dry fiber weight. Preferably, the UD layers have aramid, PBO, PBI, and/or high density polyethylene fibers and the material of the thermoplastic layers is polyethylene or polypropylene.
